ETSI Role in testing

IMS interoperability is a key issue for boosting IMS (IP Multimedia

Subsystem) roll-out and more specifically network interconnection between operators.

Only via thorough testing in practical scenarios can operators ensure operational excellence in a multi-vendor and multi-provider environment.

IMS comprises a set of specifications designed to enable network

operators to implement IP-based networks that can carry services

for both fixed and mobile customers simultaneously.

ETSI Role in testing

IMS was developed originally in the mobile world (specifically in the specifications created by the 3rd Generation Partnership Project, 3GPP), and was adopted for fixed networks by ETSI’s TISPAN Technical Committee (Telecoms & Internet Converged Services & Protocols for Advanced Networks).

Advanced communications over the next generation network will

only be delivered if those same networks can interconnect.

ETSI Role in testing Testing support to all Technical Bodies early in the process

Interoperability is best achieved when it is designed from the beginning and not “bolted-on” at the end

ETSI is recognized as world leader for Testing and Interoperability Validation of Standards through PlugtestsTM for 10 years Development of Test Specifications for over 20 years

ETSI is between Standardization and industry Interoperability and conformance together Testing methodology TTCN3 and tool prototypes

The awareness of on-going testing activities

Knowledge about test activities will give your company “the right directions”

Participating to PlugtestsTM events will get your company in the “right Place”

Participants to Plugtest have evaluated “experience comparable to more than 6 months testing”

Call For Papers has been issued (CL 2761) Call for Articles for an ETSI Book on “Success Stories in Validation and Testing”
